- There is now a variant of Kermit-370 for CICS. The new Kermit has been
- tested under releases 1.7 and 2.1 of CICS and with CICS running under
- both VSE and MVS. This is a full-function Kermit, like other variants
- of Kermit-370, but is still a test program, since it has not been
- subjected to any large-scale testing, and several planned refinements
- have not yet been implemented. Kermit-CICS is both a traditional
- interactive Kermit and a CICS program that can be invoked to carry out a
- specific file transfer or group of transfers and then quit. Thus, it is
- suitable both for "open" CICS systems where the users are permitted to
- log in as "operators" and controlled systems where all activity is
- performed through menus. Kermit-CICS surmounts the lack of a real CICS
- file system by managing its own storage directories assigned to specific
- users, where each directory has members described by eight-character
- names; the assignment of directories is done according to an algorithm
- chosen by the local installer. In addition, Kermit supports transfers
- of TD and TS queues. The initial version is release 4.2.2 and includes
- a number of enhancements that are also appearing in the new releases for
- CMS, TSO, MUSIC, and ROSCOE. However, these enhancements are not listed
- here, since this is the first version of Kermit-370 for CICS. See the
- relevant announcements for more details. Work on Kermit-CICS is
- continuing, but some of the tasks necessary for making it a full-fledged
- production program have not even been started.
-
- Features that need to be improved or added include:
-
- - IKXDYNAL for both CICS/VSE and CICS/MVS. The former would probably
- support only spool files, but the latter should support both spool
- files and MVS data sets.
-
- - Sample exit routines for supporting userid algorithms besides the
- OPID and TERM options.
-
- - Sample package of security exit routines.
-
- - Enqueuing on extra-partition TD names before opening.
-
- - Support for data objects on a remote CICS.
-
- - Cleaner performance of server-mode BYE function, dependent on local
- conventions.
-
- - Support for indirect TD queues.
-
- - Testing linemode operation.
-
- - Mechanism for flushing terminal output from Kermit (such as from the
- TYPE subcommand).
-
- - Mechanism for collecting "terminal" output from invoked programs.
-
- - Testing under CICS/VM.
-
- Anyone interested in working on these or other improvements should first
- get in touch with the Center for Computing Activities at Columbia
- University to find out if someone else has already begun a similar
- project (and, if so, who).

- Keywords: IBM 370 Kermit, CICS Kermit

-
- This is to announce the release of Kermit-370 version 4.2.4 for CICS.
- The CICS-related Kermit files that have been changed or added are as
- follows.
-
- IKXKER.ANN this message
- IKXKER.BWR bugs, warnings, and restrictions
- IKXKER.HLP Help files
- IKXKER.INS installation instructions
- IKXKER.UPD post-4.2.0 updates
- IKXTRN.ASM VSE installation utility
- IK0AAA.HLP Kermit-370 release notes
- IK0KAN.ASM optional Kanji tables
- IK0KER.ANN the accompanying message on Kermit-370
- IK0KER.UPD the cumulative list of updates in all variants
- IK0423.HLP notes on the new features in 4.2.3 and 4.2.4
-
- Many thanks to the beta testers who have helped work out the bugs in the
- new release. Note that version 4.2.3 has been available in the Kermit
- test area for several weeks. 4.2.4 differs in only two respects:
-
- (1) the KSDS used for storing the Help and TAKE files has a new, longer
- key size and will require re-installation for sites that have the
- old Help files installed. See IKXKER.INS for the details. The
- reason for the change is the expansion of the "userid" field in
- Kermit from four to eight bytes.
-
- (2) an extra message has been added to the usual protocol-mode
- greetings. The added message is "KERMIT READY TO SEND..." (or
- RECEIVE or SERVE).
-
- There are several other changes specific to CICS:
-
- - Now prevents clashing simultaneous access to a TDQ by two Kermit
- sessions.
-
- - Now distinguishes between readable and writable data objects when
- determining file name collision and searching for files to download.
-
- - Now has the correct code for CICS 1.6 access to extra-partition TDQs
- under MVS.
-
- - Now pads the interactive mode prompt with XON (or whatever is the
- current HANDSHAKE character).
-
- - Now drives the 3174 AEA properly in transparent mode through VTAM.
-
- - No longer produces unpredictable results when copying to or from
- Kermit directory members.
-
- - No longer mistakes the date in March-December of even-numbered years.
-
- - No longer produces spurious error messages at installation time under
- VSE/ESA.
